Biometric Cryptosystems: Issues and Challenges
Overview In traditional cryptosystems, user authentication is based on possession of secret keys, which falls apart if the keys are not kept secret (i.e., shared with nonlegitimate users). Further, keys can be forgotten, lost, or stolen and, thus, cannot provide nonrepudiation. Current authentication systems based on physiological and behavioral characteristics of persons (known as biometrics), such as fingerprints, inherently provide solutions to many of these problems and may replace the authentication component of the traditional cryptosystems. This paper presents various methods that monolithically bind a cryptographic key with the biometric template of a user stored in the database in such a way that the key cannot be revealed without a successful biometric authentication.
